CORSET-STEEL CLASP OR FASTENING.

SPECIFICATION forming part of Letters Patent No. 316,148, dated April. 21, 1885.

Application filedFebruary 9 1885. (No model.)

To aZZ whom it may concern.-

Be it known that I, LUOIAN HILL, of North Brookfield, county of \Vorcester, State of Massachusetts, have invented an Improvement in Corset-Steel Fastenings or Clasps, of which the following description, in connection with the accompanying drawings, is a specifi' cation, like letters on the drawings representing like parts.

Corset -steel fastenings such as heretofore employed and made from sheet metal have commonly had an elongated slot contracted between its ends to co-operate with a headed stud or peg fastened to one of the steels, the said stud or peg being drawn through the said slot from end to end. In my present invention I attach to one steel a jaw provided with a hole a little smaller in diameter than the diameter of'the headed stud which is attached to the other steel, and to fasten the front of the corset together the said jaw, placed with the said hole just above the head of the stud, is pushed down upon the head of the stud with sufficient force to cause the arms of the jaw to separate and pass belowthe part of the stud of largest diameter, and thereafter the jaw contracts below the said head, forming a secure fastening.

Figure 1 represents in top view portions of two steels, with an attached fastening embodying my invention, the parts being caught together. Fig. 2 shows the said parts unhooked. Fig. 3 is a section on the linear m, Fig. 1; and Fig. 4 a view of the outer end of thejaw.

The steels a b are of usual construction. The jaw 0 is composed of a plate having a substantially round hole, 2, slotted each way from the said hole, as shown at 3 4, to constitute a spring-jaw. The jaw is attached to the steel a by rivets 5, and in completing the said hole 2 the metal about it will preferably be countersunk, and one end of one arm of the spring-jaw will preferably be provided with a lug, 6, to enter a groove, 7, in the other arm oppositeto it, to prevent one arm being bent upward or downward by pressure exerted thereon when the stud is entering the jaw or is disengaged from the jaw. The steel 12 has attached to it a stud, d, having an enlarged substantially round head of a diameter in excess of the hole 2, made between the arms of the jaw, so that when the said hole2 is placed directly above and with the under side of the jaw in contact with the head of the stud pressure of the jaw against the stud in the direction of the length of the latter causes the jaw to expand or separate and pass below the head of the stud, the said jaw thereafter closing together below the head of the stud. In this invention the stud does not have a longitudi- 6o nal movement in the opening of the plate or between the arms of the jaw.

I claim- 1. A corset steel having attached to it a plate provided with asubstantially round hole, 6 and having a narrow slit leading out from the said eye to form the plate into a spring-jaw, combined with asecond or opposed steel having a stud with an enlarged head to be forced longitudinally through the hole 2 of the said plate in the direction of its thickness and between the arms of the jaw, the latter springingtogether below the said head and operating to retain the stud in said hole, substantially as described.

2. In a corset-steel fastening, a steel having an attached plate provided with a countersunk eye and a narrow slot intersecting the said eye, as shown, forming the plateintojaws, combined with steel 1) and its attached headed stud of a diameter greater than the eye of the plate, the stud having the rounded head and entering the eye only in the direction of the thickness of the plate, all operating substantially as shown and described.

In testimony whereofl have signed my name to this specificationin the presence of two subscribing witnesses.

LUCIAN HILL.
